<DIV><SPAN class=619420816-25022004>For a long time I've harbored the notion
that leaving the rudder cable wires, and the like, ungrounded was a source
of problems for those that have them. I've never done the experiment, 'cause I
haven't had the problem. I do run my antennas in a tube that is run up at
the very top of the fuse, and up the L.E. of the fin: steel rudder cables,
carbon elevator rods and all.</SPAN></DIV>

<DIV>I've no experience with the full carbon fuse - antenna issue. However, a
few years ago I experienced all sorts of range / glitching problems in an
airplane that had metallic paint, metal cables and other potential points of
metal - metal contacts (landing gear, landing gear door mechanisms, etc.)
Running the antenna through a wing helped a bunch, as it moved the antenna
away from noise generators. The real fix was to wire all metal objects
together with a "ground wire" that was connected to the negative battery lead.
Antenna then worked fine inside the fuse. All this was with an AM receiver on
6-meters. </DIV>
<DIV> </DIV>
<DIV>A similar experience occurred with a different airplane that had a small
fuselage and a lot of servo leads near a good portion of the antenna, range
was nonexistent until moving the antenna to the wing. In this case the
receiver was single conversion FM on 6-meters.</DIV>
<DIV> </DIV>
<DIV>My conclusions were that the metallic paint is not a problem, metal to
metal generated noise is (at lease with AM), and antenna - servo lead
proximity can be. </DIV>
<DIV> </DIV>
<DIV>I've not had any problems with dual-conversion FM on 6-meters with the
antenna inside or outside the fuse, although I maintain a couple of
inches separation between servo leads - cables and the antenna. </DIV>
<DIV> </DIV>
<DIV>Current flights with the Partner haven't demonstrated any issues with the
antenna inside the Kevlar rear of the fuse (as expected), although I've flown
head on trimming stuff that has put the carbon front of the fuse between the
antennae.</DIV>
